If you create a new task using the regular Task initializer, your work starts running immediately and inherits the priority of the caller, any task local values, and its ...

Using async/await in Swift allows us to write asynchronous code that is easy to read and understand, but by itself it doesn’t enable us to run anything concurrently – even w...

Swift tries to ensure access to shared data is done safely, partly through types such as actors, and partly through a concept of sendability implemented through the ...

Swift's full range of concurrency features work great with unit tests using both the legacy XCTest framework and the new Swift Testing framework.Swift 的全套并发功能非常适合使用旧...

Concurrent Swift code often streams values over time rather than returning them all at once, so it's important to be able to write tests to check an AsyncStream, AsyncSeq...

Swift tasks can have a priority attached to them, such as .high or .background, but the priority can also be nil if no specific priority was assigned. This...

Sometimes you want to run several async operations at the same time then wait for their results to come back, and the easiest way to do that is with async let. This lets you start...

When a thread pauses work on one actor to start work on another actor instead, we call it actor hopping, and it will happen any time one actor calls another.当线程暂停对一个 a...

Just as Swift’s functions can be asynchronous, computed properties can also be asynchronous: attempting to access them must also use await or similar, and may also need&...

When you're dealing with older concurrency code that relies on callback functions that get run when some work completes rather than using Swift concurrency's async/await ...
